Title: Logic circuit device
Inventor: SHIRASAGO TOSHIAKI
IPC: H04N5/00
Filed: 1989-11-13
Abstract: PURPOSE:To effectively advance a logical verification by stabilizing an output of a register without leaving it unstable, during the time until data is latched be a register which cannot apply the system reset. CONSTITUTION:The logic circuit device is provided with an initial signal generating circuit 3 for generating an initial signal by receiving a system reset signal, a mask signal generating circuit 4 for inputting the initial signal and a latch signal L and generating a mask signal QM, and a gate circuit 5 which is brought to gate control by the mask signal QM and controls a transfer to a circuit body part 2 of an output QX of a register 1. In a period until first data is latched to a register which cannot apply the system reset, a transfer to the next stage circuit of an output of the register being in an unstable state is obstructed, and some determined signal from the gate circuit under the condition that no mask signal is generated is applied stably to the circuit body part 2. In such a way, the whole logic circuit is stabilized and its logical verification can be executed efficiently.

Title: Sheet conveying device of transfer type recorder
Inventor: TANABE EIICHI
IPC: B41J17/38
Filed: 1988-11-18
Abstract: PURPOSE:To stabilize a posture of a recording sheet in peeling by a method wherein a radius of curvature at a part of peeling a transfer sheet off from a recording sheet of a peeling bar is specified. CONSTITUTION:A peeling bar 7 has a different level part 8 at both ends, and this different level part 8 is fixed to a frame of a duplicating machine body. Each angular part 9 of this hexagonal bar is ground and has roundness of 0.2 to 0.5mm in radius of curvature R. That is, in the case of a sharp edge with less than 0.2mm in radius of curvature R, flaws are easily caused by contact with other member, appliances, etc., in transporting, assembling, inspection repairing, etc., of the machine body. Further, when the edge is too sharp, polyethyleneterephthalate, i.e., a base material of an ink donor film 10 is scraped with the edge, and scraped off powder comes easy to be stuck to the edge. Besides in the case of over 0.5mm in radius of curvature R, a recording sheet is not stabilized. Time for which peeling force acts on the recording sheet is thus shortened. Then, the recording sheet is never bent by following a transfer sheet, and rectilinear propagation property of the recording sheet is maintained.

Title: Pn junction diode and method for evaluating semiconductor substrate using the same
Inventor: ISHIZAKA KAZUNORI
IPC: H01L21/66
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of a leak current at the periphery, by providing a region having a high dopant concentration for an area narrower than that of a pn junction diode directly below the pn junction diode which is formed on the surface of a semiconductor substrate. SOLUTION: A p-type 6 inch substrate 3 is prepared by using a silicon wafer having a boron concentration of 1.5×10<15> /cm<3> , boron is implanted partially on the front side of the wafer and a p-type well region 2 (boron concentration is 2×10<16> /cm<3> ) is formed by high temperature process. Then, phosphorus is ion-implanted to a region 1 which is 1 μm wider than the boron implanted region so as to cover the entire boron implanted region 2, and diffusion process is performed. Thus, a region 1 μm narrower than the area directly below the pn junction is formed as a well region 2.  When a pn junction diode having the region 2 which has the higher dopant concentration on the substrate side is formed directly below the pn junction, the dopant concentration on the substrate side of the n-type dopant region curved line 4 at the periphery does not increase and a leak current at the periphery can be suppressed.

Title: Transistor
Inventor: KUROSAWA SUSUMU
IPC: H01L21/331
Filed: 1987-11-20
Abstract: PURPOSE:To obtain high rapidity, high hFE and short storage time in the low current range of a transistor by setting low impurity concentration of its base region. CONSTITUTION:The peak value of impurity concentration of a base region 3 is ranged from 2X10<16>cm<3> to 1X10<17>cm<3>, and set to a lower value than the peak value. Accordingly, the mobility of carrier is high and the capacity of a junction is small. Since an apparent base width is wide, electric characteristics are relatively not affected by the influence of manufacturing conditions and a danger of a short-circuit between a collector and an emitter is small, its manufacturing yield is high. Since the electric characteristics are not considerably altered even if the impurity is rediffused, its complementary structure can be easily performed. A substantial base width is determined by a depleted layer from an emitter region 1 and a collector region 3, and since the width can be sufficiently narrowed, high frequency characteristics of high performance can be induced.

Title: Semiconductor device, manufacturing method thereof, and lead frame therefor
Inventor: IWATANI AKIHIKO
IPC: H01L23/50
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To keep a standard value of max. width with dams disposed near the cavity periphery. SOLUTION: In an SOJ IC 10, small width parts 9 are formed near resin seals 17 at both ends of each outer lead 8, dam cuts 10b are formed in the small width parts 9. Each outer lead 8 is bent in the dam cut 10b. The width of the small width part 9 is set to be less than a reference value of the outer lead 8. The dams are disposed near the resin seals 17 and hence thick burrs formed in the gaps between the outer leads 8 and between the dam and the resin seal 17 can be made very small enough to avoid dropping the burrs from the seals 17. The dam cuts 10b are bent to cause plastically deformed protrusions 10c remaining in the small width parts, without extruding outside over the reference size of the outer lead 8. Thus, the reference value of max. width of the outer leads 8 can be maintained whereas the dam cuts 10b are bent.

Title: Detecting device for extremely small defect of thin wire
Inventor: SUMI KOHEI
IPC: G01B11/30
Filed: 1989-11-10
Abstract: PURPOSE:To detect the defect of the thin wire over a wide range with high accuracy and high reliability by providing a cylindrical lens group, a light shield plate, and a device which reduces and detects the disorder of a Fourier pattern due to scattered light. CONSTITUTION:A light source 2 emits single-wavelength laser light and when the light is transmitted through the cylindrical lens group 3, the light spreads into a plane in the lengthwise direction of a body 1 to be measured to become laser light which is thicker than the body 1 to be measured. The laser light is scattered by the body 1 to be measured and is reduced and imaged on the image pickup surface of a TV camera 5 through a lens 4 as a Fourier- transformed image pattern. At this time, laser light which travels straight at the periphery of the body to be measured is cut off by the light shield plate 6. The Fourier pattern of the image is sent as a video signal to an image processor 8 and sent to a monitor TV. The Fourier pattern is disordered by an extremely small defect of the body to be measured and the disorder is recognized by an image recognizing device 8 to detect the defect. When the body is irradiated with laser light beams in two directions, the detection dead angle is reducible and the thin wire defect can be detected with higher accuracy.
